The number of bacteria in a certain population increases according to a continuous exponential growth model, with a growth rate parameter of
6.1%
per hour. how many hours does it take for the size of the sample to

note: this is a continuous exponential growth model.
do not round any intermediate computations, and round your answer to the nearest hundredth.

The system of equations graphed below has how many solutions? y = 2x + 2

Phyllis and chen are saving money to go to a football game. each friend starts with some money and saves a specific amount each week. phyllis made a graph to show the total she has saved at the end of each week. chen wrote an equation to show the total, y, he has saved at the end of each week, x. y = 15x + 15 compare the amount that each friend has when both friends start saving. select the correct answer from the drop-down menu to complete the statement. phyllis starts with $ and chen starts with $

Determine the number of outcomes in the event. decide whether the event is a simple event or not. upper a computer is used to select randomly a number between 1 and 9 comma inclusive. event upper b is selecting a number greater than 4. event upper b has nothing outcome(s). is the event a simple event? (yes or no) because event upper b has (fewer than, exactly, more than) one outcome.
